以上是表單虛擬提交的方法。但是實驗了很多方法。發(fā)現(xiàn)數(shù)據(jù)post過去后無法生成Excel通過生成后下載方法也無法實現(xiàn)。（即在服務(wù)器端無法生成，但本機可以生成。）經(jīng)過多次思路的轉(zhuǎn)折后來想到通過數(shù)據(jù)分析來調(diào)試?？纯吹降讛?shù)據(jù)是否post到網(wǎng)頁

復(fù)制代碼代碼如下:

 
string tmpFileName = "export.xls"; 
string tmpContent = Request["ExportContent"]; 
if (Request["FileName"] != "") 
{ 
tmpFileName = Request["FileName"];//獲取傳遞來的文件名? 
tmpFileName = System.Web.HttpUtility.UrlEncode(Request.ContentEncoding.GetBytes(tmpFileName));//處理中文文件名的情況 
} 
Response.Clear(); 
Response.Buffer = true; 
Response.ContentType = "application/vnd.ms-excel"; 
Response.AddHeader("Content-Disposition", "attachment;filename=\"" + tmpFileName + "\""); 
Response.Charset = ""; 
System.IO.StringWriter tmpSW = new System.IO.StringWriter(); 
System.Web.UI.HtmlTextWriter tmpHTW = new System.Web.UI.HtmlTextWriter(tmpSW); 
tmpHTW.WriteLine(tmpContent); 
Response.Write(tmpSW.ToString()); 
Response.End();
